1 Product Information Data Sheet Polyurethane bonded flexible foam Issue date: March 2009 Product: Bonded foam, based on flexible polyurethane Foam, mixed with either cork, latex foam, rubber or polyurethane elastomers Description of foam type: re-bounce Manufacturer: Recticel SAS Address: Z.I. B.P.8 Mazeyrat-d Allier FR Langeac Tel/fax: +33/ / Bonded polyurethane foams should be considered as Materials or Products. They are identified as industrial polymers. Bonded polyurethane foams are not considered to be hazardous products nor as mixtures of dangerous substances. A. Product Identification Product name: Bonded polyurethane foams, based on polyether PUR, polyester PUR foam. HR (High Resilient) PUR foam, moulded hot and cold cure foam, visco-elastic foam or other polyurethane prime-foams and either rubber or polyurethane elastomers. Trade names: re-bounce Composition: Mixture of polyurethane polymer and foam, rubber or polyurethane elastomers. Chemical description: Mixture of bonded polyurethane flocks, glued together by means of a urethane-based binder system together with rubber or polyurethane elastomers. Polyurethane primefoam being produced by a poly-addition of isocyanates, polyether/polyester March 2009 rev.0 1

2 polyols and water, controlled by catalysts, stabilizers and other substances, resulting in a cellular polyurethane foam. The isocyanate and polyol are completely reacted during manufacture and foam, as supplied, contains no free isocyanate. Rubber can be added as a powder. The rubber is usually based on reground truck tyres, i.e. consisting mainly of natural rubber, carbon black and mineral fillers. Re-bounce grades can contain between 0 and 35 % of rubber powder. Polyurethane elastomers consist only of polyurethane which is a poly-addition product of isocyanates, Polyether or polyester polyols, controlled by catalysts, stabilizers and other substances, resulting in a non-cellular polyurethane elastomer. The isocyanate and polyol are completely reacted during manufacture of the elastomer and the elastomer, as supplied, does not contain free isocyanate. Re-bounce grades can contain between 0 and 35 % polyurethane elastomer Appearance: Cellular flexible foam. Regulatory Information: No labeling is currently required for this product by existing EU Directives on Classification, Packaging and Labeling of Dangerous Substances. B. Physical properties Physical form/appearance: Solid, voluminous material, more or less elastic Colour: Varies according to manufacture Specific gravity: kg/m³ Solubility in water: Insoluble Odour: None or mild odour Flash ignition point: Between 315 C to 370 C March 2009 rev.0 2

3 Decomposition temperature: Above 180 C Thermal energy: +/ KJ/kg Stability and reactivity: The product is stable at temperatures between - 40 C and +120 C C. Fire Hazards identification Auto-ignition point : (ASTM D 1929) Between 370 C to 427 C Fire hazard: The product is a combustible material and causes, when burning, intense heat and dense smoke. Melting point: Suitable fire extinguishers: The product can, when heated also melt and flammable decomposition products can be generated. In a fire, decomposition products such as carbon black, carbon monoxide, carbon dioxide, gaseous hydrocarbons and nitrogen containing products can be generated in various concentrations depending on the combustion conditions. Also corrosive gases could be generated if the product contains flame retardants. Water, CO 2, dry powder, liquid foam. Human protection in large fires: Fire fighters should use self-contained breathing apparatus. Further fire information: Terms like is flame retarded or contains flame retardants are sometimes used to describe improved ignition resistance in small-scale tests and do not reflect hazards in large scale fire conditions. Storage & Processing: Because of the fire risks associated with certain processing operations on block foam (e.g. hot-wire cutting, crumbing, solvent lamination, etc) it is advisable to seek expert guidance on fire precautions that need to be in place.

4 D. Toxicological data Oral: There is no evidence that PU foam is toxic orally. LD50 (oral-rats) >5000 mg/kg. Inhalation: Chronic inhalation of polyurethane dust particles could cause lung infection, airway obstruction and fibrosis. Skin contact: No adverse effects known following contact with the product. Eye contact: Dust particles can cause mechanical irritation. Rinse with water to remove dust. E. Protective measures in handling, storage and processing At normal temperature the product presents no risk to health. Special protective equipment and clothing is not necessary when handling foam, since it does not irritate the skin, eyes or respiratory system except in those processes where dust is generated. Ventilation: Provided there is adequate general ventilation, no special precautions are necessary for most handling and cutting operations. Ventilation during some operations: Local exhaust ventilation is necessary for some operations i.e. where dust is generated from buffing and flocking operations or where fumes are produced in flame laminating, thermoforming and hot wire cutting. Storage: Store away from heat sources (match, cigarette, open fire, electrical heater, ). UV rays may cause surface discoloration. Eye protection: Protective goggles should be worn for processes, which generate dust. March 2009 rev.0 4

5 Protective clothing: Not required. See also section C dealing with Fire Hazards. F. Ecological information Biodegradability: Under normal conditions of use, the product is not degradable or degrades slowly. G. Transport information Labelling: The product is not classified for conveyance or supply under the Carriage of Dangerous Goods (classification, packaging and labelling) and Use of Transportable Pressure Receptacles Regulations The product is not classified as hazardous for any mode of transportation under current EU/UN regulations by applying the appropriate test method. Measures: No special steps need to be taken for the transportation of PU foam. H. Disposal considerations Production trim: Trim of the product and off-cuts can usually be recycled by several methods if uncontaminated by extraneous matter. Post Consumer Waste: A recycling option exists via rebonding if a series technical and economical conditions are met. If recycling is not possible, scrap or post consumer product waste can be disposed of at licensed landfill sites or by incineration under controlled conditions. Advice on the preferred method should be sought from the Local Waste Regulation Authority. Legislation: Check local legislation for the disposal of the product. March 2009 rev.0 5
